waterproof:closed foam polestructure,non-waterabsorption,moistureproof,perfectwater-tolerant.

corrosion resistance:resistance to sea water,oil acid,alkali andother chemicalscorrosion,antibiosis,non-toxic,tasteless,pollution-free.

workability:without joint,easy tohot-press,clipping,glueing,fit.

shockproof:rebound elasticity and high tensile strength,hightoughness,good shock/buffer performance.

heat preservation???thermal insulation???protection against lowtemperatures and low temperature performance is

sound insulation:closed foam,sound insulation effet isgood.
